In this video you see a an orbital line (going through a pulley) this is associated with the OKE winch, and a tether line (runs through the center face of the OKE) This can be the KiteGen’s winch in this example.
You can see in this arrangment how it can rotate without twisting, (or under active control it could rotate along with the axis of the kite, always keeping lines straight). But the Winch can be configured to also Reel both lines (as shown below).
